hgweb/localrepo: pass the request object to hooks

The pretxnchangegroup hook is main place to do authorization based on the
contents of the commit, such as named branches, committer etc. In order to
receive authorization headers you need access to the environment. With CGI
you can always use os.environ, but not so with WSGI.

localrepo gets a property, request, which is normally None, but can be set
to an object which is then passed on to hooks. hgweb sets it when processing
requests.
